Qhov sib txawv tseem ceeb ntawm cov phab ntsa ntawm tes thiab cov cell membrane yog cov phab ntsa ntawm tes yog cov txheej txheem cell permeable muaj nyob rau hauv cov kab mob, nroj tsuag, fungi thiab algae thaum lub cell membrane yog ib qho kev xaiv permeable membrane muaj nyob rau hauv txhua hom cell nrog rau tsiaj hlwb.

Cell membrane (plasma membrane) thiab cell phab ntsa yog cov txheej txheem sab nraud uas cais cov cell organelles los ntawm ib puag ncig sab nraud. Cov khaubncaws sab nraud povtseg tshwj xeeb no muab cov duab zoo rau cov hlwb, thiab tseem ua raws li cov khoom siv tiv thaiv kev tiv thaiv lub cev hauv lub cev. Txawm li cas los xij, tsis zoo li cov cell membrane uas muaj nyob rau hauv txhua hom cell, phab ntsa ntawm tes tsuas yog muaj nyob rau hauv lub hlwb ntawm cov nroj tsuag, fungi thiab feem ntau protists, tsuas yog cov tsiaj cell. Kab lus no yuav tham txog qhov sib txawv ntawm cov phab ntsa ntawm tes thiab cov cell membrane hauv cov tsiaj thiab cov nroj tsuag kom meej.

Lub Cell Phab Ntsa yog dab tsi?

Cell phab ntsa yog txheej txheej sab nraud ntawm ntau lub hlwb tshwj tsis yog hauv cov tsiaj hlwb. Cov kab mob, cov nroj tsuag, fungi thiab feem ntau cov protists muaj cov phab ntsa ntawm tes nyob ib puag ncig cov cell membrane ntawm lawv cov hlwb. Structurally, nws yog ib tug nruj txheej uas muab ib tug meej zoo rau lub cell. Txawm li cas los xij, muaj pes tsawg leeg ntawm cov phab ntsa ntawm tes sib txawv ntawm cov kab mob sib txawv. Peptidoglycan yog lub ntsiab lus tseem ceeb uas muaj nyob rau hauv cov kab mob ntawm phab ntsa. Nyob rau hauv sib piv, chitin yog lub ntsiab tivthaiv tam sim no nyob rau hauv lub fungal cell phab ntsa. Cog cell phab ntsa muaj cellulose ua nws lub ntsiab compound. Ib yam li ntawd, cov ntsiab lus tseem ceeb uas muab cov yam ntxwv zoo rau lawv cov phab ntsa ntawm tes sib txawv ntawm cov pab pawg ntawm cov kab mob thiab ua kom yooj yim rau kev txheeb xyuas.

Daim duab 01: Cog Cell Wall

Tsis zoo li cov cell membrane, cell phab ntsa yog ib txheej permeable tag nrho. Nws tsis xaiv cov tebchaw uas nkag mus rau hauv thiab tawm ntawm tes. Txawm li cas los xij, nws tiv thaiv cov hlwb los ntawm tawg. Txij li cov phab ntsa ntawm tes yog txheej txheej txheej feem ntau tam sim no nyob rau hauv ntau lub hlwb, nws ua tiav ntau yam haujlwm xws li muab cov qauv tsim muaj zog, muab cov duab meej rau ntawm tes, thiab tiv thaiv lub xov tooj ntawm cov kab mob thiab cov neeg kho tshuab raug mob, thiab lwm yam.

Cell Membrane yog dab tsi?

Cell membrane los yog plasma membrane yog ib txheej txheej permeable xaiv nyob rau hauv tag nrho cov feem ntau ntawm tes. Nws encloses lub cell thiab cais nws cov ntsiab lus los ntawm ib puag ncig sab nraud. Ntxiv mus, nws yog ib daim nyias nyias, uas yog li ntawm 5 mus rau 10 nm tuab. Raws li txoj cai, nws yog phospholipid bilayer. Sib nrug los ntawm ob nplooj ntawv ntawm phospholipid molecules, ob hom protein molecules kuj muaj nyob rau hauv cell membrane. Lawv yog cov muaj protein ntau thiab peripheral proteins. Ntawm ob hom no, cov proteins ib txwm txuas mus tas li nrog phospholipid txheej thaum lub peripheral proteins ib ntus txuas nrog phospholipid txheej. Qee cov proteins ib txwm yog transmembrane proteins uas hla thoob plaws phospholipid bilayer. Tus qauv "cov kua dej mosaic" yog cov qauv uas piav qhia txog cov qauv saum toj no ntawm cov cell membrane.

Daim duab 02: Cell Membrane

Tag nrho cov khoom ntawm cov cell membrane muab ob peb lwm yam haujlwm uas tsis yog kev txhawb nqa thiab kev tiv thaiv. Tshwj xeeb tshaj yog, transmembrane proteins ua raws li cov cab kuj cov proteins uas pab txhawb lub membrane kev thauj mus los ntawm molecules. Lawv koom nrog kev thauj mus los tsis muaj zog, thiab lawv kuj ua haujlwm raws li cov channel proteins thiab receptor proteins. Ntxiv nrog rau cov protein thiab phospholipids, muaj cov carbohydrate chains uas koom nrog cov proteins (glycoproteins) thiab lipid bilayer (glycolipids) ntawm cov cell membrane. Yeej, lawv yog ib qho tseem ceeb nyob rau hauv 'tus kheej' paub thiab paub cov ntaub so ntswg ntawm cov hlwb. Tsis tas li ntawd, muaj qee cov lipid molecules hu ua cholesterol thiab glycolipids uas pab cov qauv ntawm cov cell membrane.

Dab tsi zoo sib xws ntawm Cell Phab Ntsa thiab Cell Membrane?

  • Cell phab ntsa thiab cell membrane yog ib feem ntawm cov hlwb.
  • Lawv yog cov khaubncaws sab nraud povtseg ntawm lub cell los ntawm ib puag ncig sab nraud.
  • Tsis tas li, lawv nyob ib puag ncig ntawm lub cell sab hauv.
  • Ntxiv mus, ob txheej tso cai rau cov molecules nkag mus rau hauv thiab tawm ntawm tes.
  • Ob leeg muaj ntau yam sib xyaw
  • Dhau li ntawd, lawv muab kev txhawb nqa rau lub cell.

Qhov txawv ntawm Cell Phab Ntsa thiab Cell Membrane yog dab tsi?

Ib lub cell muaj qhov sib txawv. Ntawm lawv, cell phab ntsa thiab cell membrane yog ob qho tseem ceeb ntawm lub cell. Txawm li cas los xij, tsiaj hlwb tsis muaj phab ntsa ntawm tes tsis zoo li cov nroj tsuag, fungal, algal thiab kab mob hlwb. Yog li ntawd, cell phab ntsa yog txheej sab nraud ntawm cov nroj tsuag, fungal, kab mob thiab algal hlwb thaum lub cell membrane yog txheej sab nraud ntawm cov tsiaj hlwb. Yog li, qhov no yog qhov sib txawv ntawm cov phab ntsa cell thiab cell membrane. Txawm li cas los xij, qhov sib txawv tseem ceeb ntawm cov phab ntsa cell thiab cell membrane nyob nrog lawv cov permeability. Lub cell phab ntsa yog permeable kiag li thaum lub cell membrane yog xaiv los yog ib nrab permeable.

Lwm qhov sib txawv ntawm cov phab ntsa cell thiab cell membrane yog cov muaj pes tsawg leeg. Qhov ntawd yog; Lub cell phab ntsa muaj cellulose, chitin, peptidoglycan, thiab lwm yam thaum lub cell membrane muaj phospholipids, proteins, carbohydrates, thiab lwm yam.

Summary – Cell Phab vs Cell Membrane

Cell phab ntsa yog ib qho permeable barrier uas npog cov nroj tsuag, fungal, kab mob thiab algal hlwb. Piv txwv li, cell membrane yog ib feem thiab xaiv permeable barrier nyob rau hauv tag nrho cov hom ntawm tes. Qhov no yog qhov sib txawv loj ntawm cell phab ntsa thiab cell membrane. Tsis tas li ntawd, cov phab ntsa ntawm tes yog tsim los ntawm cellulose, chitin, peptidoglycan, thiab lwm yam, thaum lub cell membrane yog tsim los ntawm phospholipids, proteins, carbohydrates thiab lipids. Ob lub cell phab ntsa thiab cell membrane tiv thaiv lub cell sab hauv los ntawm ib puag ncig sab nraud.
